I'm stumped. I replaced each rear axle's bearings and seals as well as replaced the hydraulic fluid and filter. Upon attempting the first engine start there is a grinding sound coming from beneath the tractor. I'm quickly stopped cranking, but have attempted it a few more times in hopes of locating the exact location of the sound, which I haven't been able to locate. I verified that the PTO engage lever is disabled, and transmission gear is in neutral, thinking I might have bumped them during the maintenance, and perhaps it's a fluke that the engine would engine. I lifted the rear of the tractor and rotated the rear wheels and they spin freely without an noticeable grinding noise or resistance. During the maintenance, I ensured that the bearings seated properly and the cir-clips seated in their groves as required. I'm thinking about removing the drive shaft from the engine to the transmission and attempting a start to help troubleshoot the issue. If you have recommendations or ideas, please respond. Thank you!

See if it is the starter. Sometimes the bendix gear gets jammed up and doesn’t engage properly. They can make a heck of a noise.
If starter is easy to remove just remove it and look at it. You can also just “jump it” from battery cable to the solenoid spade to see if it makes a racket without the tractor starting.
Just be real careful about that if you’re not experienced with it, you are bypassing all safety features on the tractor.

Russell,
Thank you for the quick reply and recommendations. I decided to remove the belly mower and lay down on the ground to watch the drive shaft as I turned the key. Thankfully the tractor is small enough that I could do this by myself. The moment I turned the key, I identified the problem - a hydraulic line was in the path of the transmission cooling fan blades. As the drive shaft turned, the fan blades were skimming the line and causing the noise. A few zip ties later and all is running top notch!
